A review on selective laser sintering/melting (SLS/SLM) of aluminium alloy powders: Processing, microstructure, and properties
TL;DR: In this article, the state of the art in selective laser sintering/melting (SLS/SLM) processing of aluminium powders is reviewed from different perspectives, including powder metallurgy (P/M), pulsed electric current (PECS), and laser welding of aluminium alloys.
Journal ArticleDOI
Dislocation network in additive manufactured steel breaks strength–ductility trade-off
Leifeng Liu,Qingqing Ding,Yuan Zhong,Ji Zou,Jing Wu,Yu-Lung Chiu,Jixue Li,Ze Zhang,Qian Yu,Zhijian Shen +9 more
TL;DR: In this article, the authors show that the pre-existing dislocation network, which maintains its configuration during the entire plastic deformation, is an ideal modulator that is able to slow down but not entirely block the dislocation motion.
Journal ArticleDOI
Critical review of automotive steels spot welding: process, structure and properties
TL;DR: In this article, the fundamental understanding of structure-properties relationship in automotive steels resistance spot welds is discussed. And a brief review of friction stir spot welding, as an alternative to RSW, is also included.
Journal ArticleDOI
Revisiting fundamental welding concepts to improve additive manufacturing: From theory to practice
TL;DR: In this article, a unified equation to compute the energy density is proposed to compare works performed with distinct equipment and experimental conditions, covering the major process parameters: power, travel speed, heat source dimension, hatch distance, deposited layer thickness and material grain size.
Journal ArticleDOI
Using deep neural network with small dataset to predict material defects
TL;DR: This study attempted to predict solidification defects by DNN regression with a small dataset that contains 487 data points and found that a pre-trained and fine-tuned DNN shows better generalization performance over shallow neural network, support vector machine, and DNN trained by conventional methods.

Journal ArticleDOI
Transient liquid phase bonding of 304 stainless steel using a Co-based interlayer
TL;DR: In this paper, the effect of bonding time and solid-state homogenisation time on the microstructure and mechanical properties of AISI 304 austenitic stainless steel was investigated.
Journal ArticleDOI
Liquation Cracking in Arc and Friction-Stir Welding of Mg-Zn Alloys
TL;DR: In this paper, a study was conducted to study liquation and liquation cracking in Mg alloys during arc welding and friction-stir welding (FSW), where binary Mg-Zn alloys were selected as a model material in view of their very low eutectic temperature of 613 K (340 K).
Journal ArticleDOI
Effect of Preheating Temperature on the Mechanical and Fracture Properties of Welded Pearlitic Rail Steels
TL;DR: In this paper, the effect of preheating temperature on the mechanical and fracture behavior, hardness, and the microstructure of slot welded pearlitic rail steels was studied, where the parent rail steel has ultimate strength, yield strength and strain to failure of 1146 MPa, 717 MPa and 9.3%, respectively.
Dissertation
Dissimilar metal welds
TL;DR: In this article, the microstructural evolution of welds made between ferritic creep resistant steels that differ in chromium content was investigated, focusing on the key alloy strengthening mechanisms and the manner in which they were affected by carbon redistribution.
Journal ArticleDOI
Effect of Post Weld Heat Treatment on Mechanical and Corrosion Behaviors of NiTi and Stainless Steel Laser-Welded Wires
TL;DR: In this paper, the effects of post weld heat treatment (PWHT) on mechanical properties and corrosion behavior of NiTi shape memory wire, laser welded to the 304 stainless steel wire were investigated.
